Surface milling machine is a equipment used to mill the surface of tube and rod, especially applicable to surface processing of continuous casting copper billet.T&R possesses skilled tube/rod straightening and finishing technology. Its many machines (such as multi-roll tube and rod straightening machine with adjustable center) have gained multiple national patents. Principal features are as follows1.Adoption of optimized compound roll system with an organic combination of contact and transition curves for determining suitable roll type. Providing a reliable guaranty for solving the head and end bending and upgrading straightening precision.2.Adoption of load adjustable double roll pressing principle, turning rigid frame into flexible frame and putting the straightening force under control, meeting the needs for straightening process and machine safety.3.The main drive uses DC motor with stepless speed regulation, and equipped with speed and current balance system, which are suitable for the straightening process.4.Hydraulic system uses constant press variable pump as source of power,with rapid oil filling by the accumulator and direct-acting overflow valve for relief of overload, with the function of pressure keeping and buffering.5.Various forms of material charging and discharging systems, and the whole set of machine can be designed according to the concrete process requirements of the customers.Accessional characteristic of Adjustable Multi-roll tube and rod straightening machineIt is adjustable in the three-dimension of the roller, the adjustable parameters include sews and bending of rollers, roller angle and center distance Meeting products with variety of specification .Accessional characteristic of 2-roll high precision rod straightening machine.The roller profile is protruding -concave curve, contain straightening and transition section. It has line-touch and hollow- bending types. All of this can realize high precision straightening for the full-length. If needing improve the surface roughness of rod ,this machine also can be used as straightening and rollfinishing machine.
